YIELDABLE JOINT.

Application filed August 8, 1919.

To all whom it may concern.'

Be it known-that I, THEoDoRE G. LIN- DERME, a citizen of the UnitedStates of America, residing at Detroit, in the county of Wayne and Stateof Michigan, have invented certain new and useful Improvements inYieldableJoints, ot which the following is a specification, referencebeing had therein to the accompanying drawings.

In my Patent No. 1,199,998, granted Oct. 3, 1916, there is disclosed abottle washing machine which includes,-fnter alia-an interior cleaningbrush and an operating mechanism therefor, the operating mechanismimparting a reciprocatory movement to the brush during a rotary movementthereof, and provision is made so that the brush may yield or slip inits reciprocatory movement when a cork, closure or other obstacle isencountered at the neck of the bottle.

The object of the present invention 1s to provide a more simple, durableand yieldable joint than that disclosed in my former patent abovereferred to. The present joint is not only applicable to bottle washingmachines, but capable of general use.` especially when a reciprocatorymember slides on a rotary or stationary member and it is desired to havethe actuating means of the reciprocatory member automatically releasethe reciprocatory member.

The above and other objects are attained by a mechanical constructionthat will be hereinafter considered and then claimed, and reference willnow be had to the drawing. wherein-l Figure 1 is a vertical sectionalview of the yieldable joint; l

Fig. 2 is a horizontal sectional view of a portion of the same;

Fig. 3 is a vertical sectional view of the yieldable joint on a smallerscale, showing the joint as .having yielded or slipped;

Fig. 4 is a perspective view of the detached retainer;

Fig. 5 is a perspective view of a detached slitted slip member, and

. Fig. 6 is a perspective view of a detached yieldable member.

Since my yieldable joint has been especially designed for bottle washingor cleaning machines,y for instance of the type dis closed in my priorPatent No. 1,199,998, I have shown in this application certain parts ofthe machine so that the yielda'ble joint Specification of LettersPatent.

may be identified therewith, but the illustrated parts have beenslightly changed as will be noted hereinafter.

In the drawing, the reference numeral 1 denotes a rotary tubular memberand slid-v able on said member is a reciprocatory member 2 which has thelower end thereof reduced, as at 3, and the reduced portion providedwith diametrically opposed longitudinal slots 4.

Fixed on the reduced end 3 of the reciprocatory member 2 is a slitted orslotted slip member 5, said member having longitudinal slits or slots 6adapted to normally register with the slots 4 in the reciprocatorymember 2. The upper end of the slip member 5 is provided with acylindrical head 7 with theupper and lower ends thereof beveled, as at 8and 9. In the slip member 5 are opposed longitudinal keys or splineslOwhich extend through the slots 4 of the reciprocatory member 2, andengage in lon` gitudinal keyways or grooves 11 in the ro` tary member 1,thereby establishing a rotary `driving relation between the rotarymember 1, thev reciprocatory member 2 and the slip member 5, whereby allof said members may be revolved in unison while the members 2 and 5 arereciprocated on the member 1.

To reciprocate the member 2, I employ a cylindrical housing 12, and saidhousing is rotatable in a trunnioned collar 13 carried by the arms 14 ofa presser head (not shown). The lower end of the housing 12 formed witha peripheral langel whichV limits its insertion in the collar 13 andthus correctly positions said housing therein. The upper end of thehousing is reduced and exteriorly screwthreaded, as at 16, so as to havea sliding tit on the reciprocatory member 2 and at the same timeaccommodate a retaining washer 17 and a nut 18,

v said washer and nut constituting means on the upper end of thehousingto retain it in engagement with the trunnioned collar 13, consequentlysaid retaining means will cooperate with the flange 15 in preventingaccidental displacement'oi the housing.

The housing 12 provides a cylindrical chamber 19 and the upper wall ofsaid chamber has diametrically opposed slots 19a and a recess 2O whichprovides clearance for the head 7 of the slip member 5. In the lower endof the chamber 19 is mounted a slotted retainer 21, said retainer havinga central bore 22 providing clearance 'for the slip member and sideslots 23 alining with the slots 19a for yieldable members 24. Theretainer 21 is of less depth than the cham* ber 19 so that the yieldablemembers V24 may occupy the upper portion of said chamber, and saidmembers are diametricall-yopposed and somewhat pawl-lilre .in action.The members 24 are supported by a circular coiled spring 25 whichsurrounds the slip member 5 and` normallyengages the lower beveled e-nd`9 of the slip member head 7, as shown in Fig. 1, said spring being heldbetween the lupper wall of the chamber and the upper end of the retainer21. In this position off the slip member relative to the housing 12, theupper ends oi the yieldable members 24 engage the side walls of the head7 and the lower beveled ends 26 of said yieldable members extend intotheslots 23 of the retainer 21 and into the slits or slots G of the slipmember 5, thereby establishing ,a driving relation between the retainer2l and the slip member 5. Since the retainer 21 is fixed in the housingl2, said housing mayprevo'lve in its trunnioned collar.

The circular coiled spring 25 which snugly embraces the slip member 5constitutes a yieldable support for the slip member 5 as Vsaid` coiledspring rests on the upper end of the retainer 21. Besides, the yieldablemem,` bers 24 are fitted on the coiled spring 25 and if necessary may besolderedor otherwise connected to certain convolutions of said spring,however, the yieldable members 24 are` supported on the coiled springwith the ends thereof extending into the slots 19a and 23 and in thismanner the yieldable members 24 are held against displacement withinthehousing 12.

The rotary member 1 may have movement imparted thereto at any place solong as itdoes not interfere with the reciprocatory1 movement of themember 2, and it is possible toimpart movement to the rotary member 1through the medium of the housing 1.2 which may revolve in itstrunnioned col.- lar 13. i

Assuming that in raising the rcciprocatory Vmember 2 that someobstruction or obstacle is encountered thereby. a retardation in themovement of the reciprocatory member 2 causes the upwardly movingyieldable support 25 andL yieldable members 24 torecede, the springconstituting a yieldable support 25 expanding'to such an extent as topermit of the head 7 of the slip member .passing through', said' spring.This movement or" the headjl is facilitated by the upper beveledI endoiY said' head and in consequence of said' l'iead" expanding the springor yieldable support 25, the yieldable members24 are carried outwardly,thereby removing the lower beveled ends 26 of said yieldable membersfrom the slits or slots 6 of the slip member 5, as best shown in Fig. 3.The slip member 5 may continue to revolve the reciprocatory member 2 andthe rotary member l, but the housing 12 will remain stationary. lhen thereciprocatory member 2 recedes or is lowered, as in connection `with mybottle washing machine, the yieldable support 25 again rides over thehead 7 ot' the slip member 5 and engages under said head, thus againestablishing an lactive relation between the parts` oi the yieldablejoint.

From the foregoing it will be observed that I not only disconnect avreciprocable member relative toits actuating means, butl I would have itunderstood that the struc? tural elements of my invention aresusceptible to such modifications and alterations as fall within thescope of the appended claims. What I claim is y 1. In a yieldable joint,a reeiprocatory and rotary member, a slip member adapted to raise Vsaidreciprocatory member and rotate therewith, a housing inclosing said:slip member, yieldable means in said housing normally engaging` saidvslip member so that said housing may elevate said reciprocatory member,and a yieldable support surrounding said yslip member and supportingsaid yieldable means. 2. In ayiel'dable joint, a reciprocatory androtary member, actuating means, therefor, and releasing means rotatableWith said reciprocatory member and interposed between said reciproeatorymember and its actuating means, comprising a yieldable support andopposed members carried thereby.

3. A yieldable joint comprising a reciprocatory and rotary menfiber,actuating means therefor, a slip member in said actuating means androtatable with said reciprocatory member, a' circular coiled springsupporting said slip member, and means, including op-l posed memberssupporting said` spring rela` tive to said actuating means. l.

4. A yieldable joint comprising a reciprocable and rotary housing, amember adapted to be rotated and reciprocated from said housing, a slipmember in said housing on said member, opposed members in said housingestablishing a rotary driving relation be.- tween said housing andv thefirst mentioned member, and yieldable means, supporting said opposedmembers.

5. Ina yieldable joint, a rotary member, a reciprocatory member, a slipmember articulating all ol said members for vrotating in unison,reciprocating means for said reciprocatory and slip members,` anda'eoi'led sp1-'ing 10 ing movable to and from said slip member andadapted to be actuated by said slip member to disengage said rotatingmeans so that said slip member Will be free of said rotating means.

In testimony whereof I affix my signature 15 in the presence of twoWitnesses.
